In general, yes, especially if you're a high-powered developer.

APDA does not do product support on the items they sell, and last time I
looked they didn't even pretend to.  If you ask them for data sheets they
should send them, but more often than not they can't answer questions.

No.  The MPW IIgs C and Pascal compilers only produce 65816 code.

Yes.  Although the tools by default produce Apple IIgs OMF, the assembler can
be instructed to only accept 6502 or 65C02 instructions, and a tool known as
"MakeBinIIgs" is provided which takes an OMF file and turns it into a straight
binary file.

If you're developing for a IIe, you're limited to the target machine.  You can,
of course, write code that uses the 80-column firmware, hi-res or double hi-res
graphics just as you would on a native development system.  The assembler does
not provide graphics or TTY output libraries to link in, if that is what you
are asking.  Powerful IIe graphics packages (like ESS's "Pizzazz" package,
which is targeted exclusively for eight-bit development) are available for such
things.

It depends on what you mean by "debug".  You do not run IIe code under MPW or
on the Mac in general.  You use a tool called "duplicateIIgs", a program called
"Apple File Exchange" or AppleShare file servers to get your program from the
Macintosh onto a ProDOS disk (or onto a server that the IIe target machine
can access).  There is no cross-debugger included.
